Referral source ROI calculator
Compare gross profit from a referral channel with its direct costs.
What this calculator covers
This referral source roi calculator is publisher content for UK private clinics, therapists, and physios. You supply attributable gross revenue and direct costs for the channel. It reports simple net contribution and return on spend (net / cost) using the simplified assumptions described below—not as a substitute for an accountant, solicitor, or clinical record.
Referral partnerships might involve lunch talks, sponsorship, or revenue shares. Subtract direct costs from attributable gross revenue to see simple net contribution.
Attribution is never perfect—use the same counting rules you use elsewhere.
What this model does not do
This referral source roi calculator is original publisher copy for UK private clinic administration. It does not measure creative quality or ad-auction dynamics. Ratios are only as good as how you count enquiries and bookings.
The form cannot see your contracts, payer mix, or diary software. If a clause matters and there is no field for it, the output will not include it.

- Attributable gross revenue

How it works
-
Enter attributable gross revenue
For this Referral source ROI model, enter attributable gross revenue and direct costs for the channel. Keep those definitions consistent with your diary or management accounts.
-
Read simple net contribution
The referral source roi model then reports simple net contribution and return on spend (net / cost). The arithmetic runs in your browser; we do not receive the numbers you type.
-
Check against marketing & growth records
Treat simple net contribution and return on spend (net / cost) as planning figures for marketing & growth conversations, then confirm VAT, contracts, and filings with your own records and qualified advisers.
Context and how to use this
Subtract direct channel costs from attributable gross revenue for a simple contribution view. Attribution is never perfect—document counting rules.
Add indirect costs if your finance team allocates marketing overhead.
Common questions
- Why ROI as percent of cost?
- It is a common shorthand: net contribution divided by spend. It can explode when spend is tiny—interpret carefully.
- Lag between spend and revenue?
- Align periods if you can; otherwise note the mismatch when presenting to partners.
